Lyrics:

“Sing” is the Carpenter’s cover of Joe Raposo’s original 1971 on Sesame Street song. In their version, the Carpenters omit the bilingual aspect of the song, performing in only English.
Sing, sing a song
Sing out loud, sing out strong
Sing of good things, not bad
Sing of happy, not sad

Sing, sing a song
Make it simple to last your whole life long
Don't worry that it's not good enough
For anyone else to hear
Just sing, sing a song

La la la la la
La la la la la la
La la la la la la la

Sing, sing a song (Sing, sing)
Let the world sing along
Sing of love there could be
Sing for you and for me

Sing, sing a song (La la la la la, La la la la la la, La la la la la la la)
Make it simple to last your whole life long (La la la la la, La la la la la la)
Don't worry that it's not good enough
For anyone else to hear
Just sing, sing a song

Just sing, sing a song (Ooh)
Just sing, sing a song (Ooh)

La la la la la
La la la la la la
La la la la la la la
La la la la la
La la la la la la
La la la la la la la
La la la la la
La la la la la la
La la la la la la la
La la la la la
La la la la la la
La la la la la la la
La la la la la
La la la la la la
La la la la la la la
